Bad tipper Madonna

New York waitress Katherine Taylor has written a novel, 'Rules for Saying Goodbye', in which her heroine - also called Katherine Taylor - lists the worst tippers.

Taylor confirmed through her publisher, Farrar, Straus and Giroux, that she has worked as a West Village bartender and promised all the celebrity anecdotes in her book are true.

One extract reads: "Gwyneth Paltrow came in. I wanted to tell her that I had been making a list and she was on it, but Gwyneth was not stingy, only stupid. I thought she probably couldn't calculate 15 per cent."
